The Saxon Class XIV ${\displaystyle \textstyle {\mathfrak {H}}}$T locomotives were six-coupled

As a successor to the four-coupled Saxon Class IV T the Sächsische Maschinenfabrik in Chemnitz developed a six-coupled tank locomotive. This new engine was primarily intended to be used in charge of suburban trains in the big conurbations.

From 1911 to 1921, 106 of these locomotives, built in three series, were placed in service by the Royal Saxon State Railways. At the time of its appearance, the Saxon XIV HT was the heaviest 2-6-2 in central Europe. Not only were these locomotives used to haul suburban services, but in the end they were put in charge of all types of passenger trains on branch and main lines in Saxony's central mountains.
